"We have big plans for substantial additions in 2014 continuing Michael, Franklin, and Trevor's action, mayhem, and unexpected adventures in Southern San Andreas," Rockstar said.
No new single-player content for GTAV has been announced to date. Predecessor Grand Theft Auto IV welcomed two post-release expansions: The Lost and the Damned and The Ballad of Gay Tony.
Also planned for 2014 are GTA Online Heists. Rockstar said it is currently working "very hard" to polish them as best it can before release next year, though no other details were revealed.
Rockstar also teased today that it has "much more" to announce regarding 2014 plans for GTAV and GTA Online. The developer is rumored to launch GTAV for the PC, Xbox One, and PlayStation 4 sometime in 2014. For more on GTAV, check out GameSpot's review.
